CORK-EXTRACTOR.

Application filed May 17, 1916.

'1 b (M whom it may concern:

Be it known that I, MARTIN L. KINsnY, a citizen of the United States,residing at Dos Palos, in the county of Merced, State of California,have invented certain new and useful Improvements in Cork-Extractors;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same.

This invention relates to cork extractors and has special reference to acork extractor arranged to impart a rotary motion to the cork during theextracting process.

The principal object of the invention is to provide an improved andsimplified cork extractor wiich will effect the extraction of the corkfrom a bottle by means of a twisting or spiral movement.

A second important object of the invention is to provide an improvedform of cork extractor wherein the elements used to impart a twistingmovement to the cork may be held ineffective for such movement until thecorkscrew has been properly inserted to carry these elements deep enoughinto the cork to properly produce the movement without breaking thecork.

With the above and other objects in view, as will be hereinafterapparent the invention consists in general of certain novel details ofconstruction and combinations of parts hereinafter fully described,illustrated in the accompanying drawing, and specifically claimed.

In the accompanying drawing, like characters of reference indicate likeparts in the several views, and

Figure 1 is a perspective view showing the device about to be applied toa cork;

Fig. 2 is a perspective View showing the device in position ready toextract the cork;

Fig. 3 is a detail view partly in cross section showing a portion of thedevice including the screw shank and lock bar and showing these parts inbinding engagement;

Fig. 4 is a view similar to Fig. 3 but showing the parts in releasedposition.

Fig. 5 is a section on the center line of Fig. 1 and showing therotatable knife carrying element and its journal.

In the embodiment of the invention here in illustrated there isdisclosed a screw 10 of the ordinary type and this screw is providedwith a polygonal shank 11 at the upper end Specification of LettersPatent.

Serial No. 98,076.

of which is fixed a handle 12. Between the shank and the screw is acylindrical portion forming a journal and the shank, journal, and screware formed of one piece of metal. This shank 10 is tapered and has thesmaller end of the tapered portion lying adjacent the screw and journal.The taper of the shank is very slight for purposes which will behereinafter set forth. Iotatably mounted on the journal is a transverseknife bar 14 and carried by this bar and projecting downward therefromin parallel re lation to the screw is a pair of mives 15.

These knives 15 are preferably in the form of thin blades pointed attheir lower extremities and shaped like a double-edged dagger, the edgeslying in a plane radial to the axis of the screw. Fixed above the bar 14on the shank 11 is a collar 16 which is so arranged as to preventmovement of the bar longitudinally of the shank.

It will be obvious that this collar may be fixed to the cylindricalportion of the shank if desired.

At 1? is disclosed a lock bar and this look bar is of inverted U-shapeand is provided with a central polygonal opening 18 through which passessaid shank. The legs of the lock bar are arranged to extend downwardover the sides of the knife bar 1% when it is desired to lock the knifebar to move with the shank. The opening 18 is of such size as to beslightly larger than the smaller end of the tapering shank and to fittightly on the larger end of said shank so that there will be a bindingengagement between the lock bar and the shank when the lock bar israised so that the legs are free from the sides of the knife bar andthus the latter can rotate freely with respect to the screw and shank.

In the operation of the device, when it is desired to pull a cork thelock bar is raised until it binds upon the polygonal shank. The deviceis then used as if it were an ordinary corkscrew. As the screw entersthe cork the blades will be forced downward in straight lines so as toenter the cork to the desired extent. The lock bar is then moveddownward to release from the polygonal shank and the legs of the lockbar will engage over the sides of the knife bar so that when furtherrotation is imparted to the shank the cork will be rotated as the knifebar will be locked to said shank. Thus the cork will be loosened in theneck of the bottle and by add: ing to the rotative movement a veryslight pull the cork can be'easily extracted without breaking the sameand without danger of pulling the screw out of the cork as frequentlyhappens with the ordinary corkscrew.

There has thus been provided a simple and efiicient device of the kinddescribed and for the purpose specified.

It is obvious that many minor changes may be made in the form andconstruction of the invention without departing from the materialprinciples thereof. It is not therefore desired to confine the inventionto the exact form herein shown and described but it is wished to includeall such as properly come within the scope claimed.

Having thus described the invention, what is claimed as new is 1. A corkextractor including a screw having a polygonal shank and a handle, saidshank being tapered with its smaller portion adjacent the screw, a knifecarrying element rotatable on the shank adjacent the screw, and alocking device slidably fitted on the shank and engaging said element inone position, the opening in said device fitting the larger end of theshank in binding relation when out of engagement with the element.

2. A cork extractor including a screw having a polygonal shank and ahandle, the upper end of the screw being connected to the shank by acylindrical portion constituting aijournal, the shank being tapered withthe smaller end adjacent the screw, a knife bar rotatably mounted onthejournal, knives carried by the bar and projecting downward parallelto the screw,.a collar fixed above the bar to prevent movement of thebar Verticallyvand .a lock bar of inverted U-shape and havinga centralpolygonal opening through which said shank passes, the legs-of saidlockbar being arranged to embrace the sides of the knife bar when depressed,the opening in the lock bar being of such size as to eifect bindingengagement of the lockzbar on the shank when the lock bar is raised.

In testimony whereof, I afiix my signature, in the presence of twowitnesses.
